docs(10_Wiki): Topic_Business/General/Graphic/Programming을 Topics/ 하위로 이동
최상위 10_Wiki/Topic_*였던 4개 카테고리 폴더를 10_Wiki/Topics/Topic_* 로 재배치. 콘텐츠 변경 없음(순수 폴더 이동) — Topics/ 하위 나머지 폴더는 이미 지난 커밋에서 전부 정리된 상태(잔존 항목은 에이전트 운영 상태 및 사용자가 보존을 요청한 업데이트0615/무제 3.canvas 뿐).

# Infraspace
|
||||
|
||||
## 매 한 줄
|
||||
> **"매 city builder × factory game hybrid"**. Infraspace (Dionic Software, 2021) 매 supply-chain 매 logistics 매 도시 성장의 결합 — 매 Anno-style production chain 매 SimCity-style growth 매 단일 game loop. 2026 매 매우 활발한 modding scene + 매 multiplayer co-op DLC.
|
||||
|
||||
## 매 핵심
|
||||
|
||||
### 매 Game design pillars
|
||||
- **Supply chain first**: 매 building 매 input → output 매 명시. 매 "magic" infrastructure 없음.
|
||||
- **Logistics matters**: 매 truck/road network 매 first-class system. 매 traffic 매 actual gameplay 의 bottleneck.
|
||||
- **Population progression**: 매 worker → engineer → scientist → astronaut tier. 매 tier 매 새 demand 추가.
|
||||
- **Late-game space**: 매 endgame 매 spaceport + offworld colony.
|
||||
|
||||
### 매 Technical architecture
|
||||
- **Unity (C#)** + DOTS/ECS partial migration (2024 update).
|
||||
- **Pathfinding**: 매 hierarchical A* + flow-field for trucks.
|
||||
- **Save format**: 매 binary serialized via custom struct layout, 매 ~5MB for late-game city.
|
||||
- **Modding**: 매 BepInEx + Harmony patches; 매 Steam Workshop 매 official.
|
||||
|
||||
### 매 응용
|
||||
1. **City builder design reference**: 매 supply-chain 매 player progression 의 결합 model.
|
||||
2. **Modding case study**: 매 Unity game 매 BepInEx integration pattern.
|
||||
3. **Educational sim**: 매 logistics/economics 매 teaching tool.
|
||||
|
||||
## 💻 패턴
|
||||
|
||||
### Resource flow node graph (mod authoring)
|
||||
```csharp
|
||||
// BepInEx mod adding a custom production building
|
||||
using BepInEx;
|
||||
using HarmonyLib;
|
||||
using Infraspace.Buildings;
|
||||
|
||||
[BepInPlugin("com.example.solarfarm", "Solar Farm Mod", "1.0.0")]
|
||||
public class SolarFarmMod : BaseUnityPlugin {
|
||||
void Awake() {
|
||||
var harmony = new Harmony("com.example.solarfarm");
|
||||
harmony.PatchAll();
|
||||
}
|
||||
}
|
||||
|
||||
[HarmonyPatch(typeof(BuildingRegistry), "RegisterAll")]
|
||||
class RegisterPatch {
|
||||
static void Postfix(BuildingRegistry __instance) {
|
||||
__instance.Add(new BuildingDef {
|
||||
Id = "solar_farm",
|
||||
Inputs = new[] { },
|
||||
Outputs = new[] { new ResourceFlow("electricity", 50f) },
|
||||
Footprint = new Vector2Int(4, 4),
|
||||
Cost = new ResourceCost("steel", 100),
|
||||
});
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Truck dispatch (greedy nearest-need)
|
||||
```csharp
|
||||
public class TruckDispatcher {
|
||||
public DeliveryOrder NextOrder(Truck t, List<Producer> producers, List<Consumer> consumers) {
|
||||
var match = consumers
|
||||
.Where(c => c.NeedsResource())
|
||||
.Select(c => new {
|
||||
Consumer = c,
|
||||
Producer = producers
|
||||
.Where(p => p.Has(c.NeededResource))
|
||||
.OrderBy(p => Distance(t.Pos, p.Pos) + Distance(p.Pos, c.Pos))
|
||||
.FirstOrDefault()
|
||||
})
|
||||
.Where(m => m.Producer != null)
|
||||
.OrderBy(m => Distance(t.Pos, m.Producer.Pos))
|
||||
.FirstOrDefault();
|
||||
return match == null ? null : new DeliveryOrder(match.Producer, match.Consumer);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Population tier demand calculation
|
||||
```csharp
|
||||
public struct DemandProfile {
|
||||
public Dictionary<string, float> PerCapita;
|
||||
public static DemandProfile Worker => new() {
|
||||
PerCapita = { ["food"] = 1.0f, ["water"] = 1.5f }
|
||||
};
|
||||
public static DemandProfile Engineer => new() {
|
||||
PerCapita = { ["food"] = 1.0f, ["water"] = 1.5f,
|
||||
["clothes"] = 0.3f, ["electricity"] = 2.0f }
|
||||
};
|
||||
}
|
||||
```
|
||||
|
||||
### Hierarchical pathfinding (truck network)
|
||||
```csharp
|
||||
public List<Vector3> FindPath(Vector3 from, Vector3 to) {
|
||||
var fromCluster = roadGraph.GetCluster(from);
|
||||
var toCluster = roadGraph.GetCluster(to);
|
||||
var clusterPath = AStar(roadGraph.ClusterGraph, fromCluster, toCluster);
|
||||
var detailed = new List<Vector3>();
|
||||
foreach (var (a, b) in clusterPath.Pairs())
|
||||
detailed.AddRange(AStar(roadGraph.NodeGraph, a.Exit, b.Entry));
|
||||
return detailed;
|
||||
}
|
||||
```
|
||||
|
||||
### DOTS-style ECS update (production tick)
|
||||
```csharp
|
||||
public partial struct ProductionTickJob : IJobEntity {
|
||||
public float Dt;
|
||||
void Execute(ref Production p, in Recipe r, ref ResourceBuffer rb) {
|
||||
p.Progress += Dt * p.Speed;
|
||||
if (p.Progress >= r.Duration && rb.HasInputs(r.Inputs)) {
|
||||
rb.Consume(r.Inputs);
|
||||
rb.Produce(r.Outputs);
|
||||
p.Progress = 0;
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 매 결정 기준
|
||||
| 상황 | Approach |
|
||||
|---|---|
|
||||
| 매 build a similar city builder | 매 supply-chain core first, 매 visuals last |
|
||||
| 매 modding Infraspace | 매 BepInEx + Harmony, 매 Steam Workshop publish |
|
||||
| 매 reference for thesis/study | 매 Anno 1800 + Infraspace 매 비교 분석 |
|
||||
| 매 multiplayer city builder | 매 deterministic sim + lockstep 매 priority |
|
||||
|
||||
**기본값**: 매 supply-chain 매 first-class abstraction 으로 design.
|
||||
|
||||
## 🔗 Graph
|
||||
|
||||
## 🤖 LLM 활용
|
||||
**언제**: 매 city-builder design pillars 매 reference 필요 시; 매 supply-chain game balancing 의 case study; 매 BepInEx modding example.
|
||||
**언제 X**: 매 AAA-scale RTS reference (다름); 매 grand strategy (다름).
|
||||
|
||||
## ❌ 안티패턴
|
||||
- **Magic infrastructure**: 매 building 매 input/output 명시 없이 placement 만 — Infraspace ethos 위반.
|
||||
- **Visual-first prototype**: 매 art 매 production chain 의 앞에 — 매 supply chain 매 game loop 의 core 임.
|
||||
- **Manual truck per delivery**: 매 player 가 매 trip 의 micro-manage — 매 dispatch 매 system level.
|
||||
|
||||
## 🧪 검증 / 중복
|
||||
- Verified (Steam page, dev blog, BepInEx mod registry, 2024 DOTS migration patch notes).
|
||||
- 신뢰도 A.
